M.H.
I would say I am split on this. I have a friend that has a 21 year old and a 1 year old. He was "forced" to be the live in babysitter until he moved out. In that instance, he could have been out working or going to see his friends, but had to watch his younger siblings (The 1 year old is the youngest, the other two are 7 & 4 I believe). I did not agree with that.
To watch the kids while you run to pick up from school or small grocery run is one thing. But to watch them in place of daycare is a totally differnt playing field.
